RegistryStripBTWUSB.txt Driver File Contents (WIDCOM_HK-750.zip)

BE CAREFUL - DO NOT DO THIS UNLESS YOU REALLY KNOW WHAT YOU'RE DOING

Find all instances in the registry of:

btwusb
95C7A0A0-3094-11D7-A202-00508B9D7D5A
widcomm

For each, figure out what is the appropriate tree of registry keys and delete it.

It will be necessary to use C:\WINNT\system32\regedt32.exe to add full control permission to some registry trees.

In C:\[WINDOWS|WINNT]\inf, find and remove the BTWUSB inf file(s).
Find them by searching for files containing "WIDCOMM"
The file(s) should be named oem*.inf

In C:\[WINDOWS|WINNT]\system32, delete btw_ci.dll

In C:\[WINDOWS|WINNT]\system32\drivers, delete btwusb.sys and frmupgr.sys

Then reboot
